A TTORNEK UNITED STATES PATENT onnrcn JOHN AUBLE AND CRAWFORD GORDON, OF NEW YORK, N. Y.

EXPANSION ATTACHING-PLATE FOR STEAM-RADIATOR PIPES.

To all whom it may concern:

Be it known that we, JOHN AUBLE and CRAWFORD GORDON, citizens of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Expansion Attaching-Plates for Steam-Radiator Pipes, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to steam radiators and particularly to the pipes for supplying steam thereto and returning the water of condensation; and the object of the invention is to provide an improved attaching or base plate for the pipes of radiators of this class and which is attached to the base board of a room or compartment through which the su ply and return ipes are passed horizontal y and which will permit of the expansion and contraction of said pipes without in any way interfering with the operation of the radiator or marring or otherwise injuring the base board, and which will serve as an ornamental device of this class.

The. invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of our improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a side view of a steam radiator showing its connection and showing in section a part of the wall of a com artment or room and a base board secured t ereto; Fig. 2 a front view of our improved expansion plate; Fig. 3 a section on the line 33 of Fig. 2; Fig. 4 a back view of the expansion plate; and, Fig. 5 a transverse section on the line 5-5 of Fig. 2.

In the drawing forming part of this specification, we have shown at a an ordinary steam radiator, at a a pipe for supplying steam thereto and at a a pipe for conveying away the water of condensation. We have also shown at b a part of a wall of a room or compartment of a building and at c a base board secured to said wall. Arranged in or back of the wall I) is an upright steam supply pipe d for supplying steam to radiators ocated in various rooms or compartments of the building, and at d a pipe for returning or conveying away water of condensation. The pipe (1 is connected with the radiator in Specification of Letters Patent.

the usual manner by the pi e a and the pipe 61 is connected with the ra iator in the usual manner by the pipe a The pipes a and a are passed through the base board 0 in the usual manner, said board being provided with a large opening 0 for this purpose and, in the practice of our invention, we provide an expansion plate 6 which is secured to said base board and which comprises a back member 6 and a front member 6 The back member 6 of our improved expansion plate is oblong in form and the corners thereof preferably rounded, and said back member is provided with a large central longitudinal opening 6 and composed of two separate similar side portions e each of which is provided with holes or apertures e whereby the expansion plate may be secured to the base board 0 by means of screws, nails or otherwise. The front member e of the expansion plate is of the same form as the back member 6 but is of less dimensions, the dimensions thereof being greater than the dimensions of the opening 6 in the back member c and said front member is provided with a backwardly directed flange e which bears on the back member and by which said members are separated.

The separate parts e of the'back member of the expansion plate are provided centrally of their inner edges with raised longitudinal lips f formed integrally therewith, and the front member 6 of said expansion plate is rovided centrally of its 0 posite sides with ongitudinal keepers f 2 therewith, and on the inner side thereof, and adapted to receive the lipsf and, in practice, the separate parts of the expansion plate are connected by slipping the lips f of the parts 6 of the back member 6 into the keepersf of the front member e and then securlng the backmember to the base board, and when the parts of the expansion plate are thus connected, the front member c will be free to move vertically on the part 6 within certain limits or enough to provide for the expansion and contraction of the pipes a and a The front member e of the expansion plate is provided with a top circular opening 9 through which the pipe (1. passes, and with a bottom opening 9 through which the 1pipe a passes, and the vertical diameter of w ich is greater than the transverse diameter.

When the parts are connected up as shown ormed integrally and described and steam turned on, the pipe (1 will be first heated after which the pi e a will be heated, orthese two pipes wil be heated substantially at the same time, and this will cause a greater or less vertical movement of the pipe a and this raises the front member a of the expansion plate, but the opening 9 through which the pipe a passes is of such form as to permit this movement of the front member 6 of the expansion plate, and any other movement caused by the expansion and contraction of the parts (1 and a and d and a may thus be accommodated in the expansion plate as will be readily understood. I

By means of this construction the pipes at and a are held out of contact of the base board 0, and said base board is given an attractive finish Where said pipes pass therethrough and the danger of marring or other wise injuring said base board is avoided, and

the hole or aperture in said base board through which the pipes a and a pass is entirely concealed.

Havingfully describedour invention, what we claim as new and desire to secure by Letters Patent, is

1 An attaching or base plate device for the horizontally arranged supply and return pipes of a steam radiator, comprising two plates, one ofwhich is stationary and the other vertically movable thereon, the stationary plate being provided with a large ob= long vertically arranged central opening, and the movable plate being provided with two openings arranged in vertical line, the bottom opening being oblong in form with the greater diameter thereof ran ing vertically.

2. An attaching or base p ate device for I ranged openings, the vertical diameter of the bottom opening being greater than the transverse diameter thereof.

3. A11 attaching or base plate device for I the horizontally arranged supply and return pipes of a steam radiator, comprising an obong back plate member provided with an oblong central 0 ening, and a front plate member mounte thereon and adapted to close said opening and provided with two openings arranged in vertical line, the vertigreater than the transverse diameter thereof, and said back plate member being divided longitudinally into two separate similar parts, and said parts being provided with vertically arranged guides in which the front plate member'is movable.

In testimony that we claim the foregoing as our invention we have signed our names in" presence of the subscribing witnesses this 14th day of January 1908.
